Ferromagnetic GaCrN Films Fabricated by Dual-Energy Implantation of Cr+
-
Abstract
：GaCrN ferromagnetic films with a thickness of 200nm are successfully prepared bv Cr+implantation at two ener. gies into n-GaN，p-GaN，and unintentionally doped GaN epilayers grown on sapphire substrates by MoCVD，followed by a short anneal to remove implantation damage.Powder X.ray diffraction is carried out to investigate the phase composition of the films.Magnetic properties determined from SQUID indicate a connection between the saturation magnetization and the initial carrier concentration of the samples，as in our experiment，post-implanted n.GaN and P.GaN show much stronger mag. netization than that of unintentiOnaUv doped GaN samples.-
